@suziannesaid He actually said that homosexuality is a sin against God.The difference between what he said and what I said was that I said that some men say that homosexuality is a sin against God. You know, the Pharisees.
All "sins", by their very definition, are "against God".
What theological argument, as a Christian, do you have that homosexual sex is not "sinful"?
The Buddha Dharma Education Association is crystal clear about it when they state that the "...idea of sin or original sin has no place in Buddhism." This will, no doubt, be why you "...don't recall any Zen text with a list of specific sins like in the Ten Commandments."
